GARDNER M. BURGESS, JR, OF PROVIDENCE, RHODE ISLAND.

HEELlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 331.476, dated December 1, 1885.

Application filed February 9, 1885. Serial No. 155,413. (No model.)

Be it known that I, GARDNER M. BURGESS, J r., of Providence, in the State of Rhode Island, have invented an Improvement in Heeling-Jacks, of which the following is a specification.

My invention relates to an improvement in the jacks employed for the purpose of nailing on the heels of boots and shoes in process of manufacture, and also for hand nailing the soles of the same; and my improvement consists in the combination of a pivoted springoperated arm, with an adjustable toe-rest for the last, as hereinafter set forth.

Figure l is a side elevation and partial section of the jack and the last. Fig. 2 is a front elevation without the last. Fig. 3 is a broken plan view of the same. Fig. at is a perspective view of the adjustable rest for the toe of the last.

In the accompanying drawings, A is the attaching-base of the machine, which is to be secured to a bench or table. B is a standard, extending upward for a short distance from the base A, and to the standard B is pivoted the arm 0, which is provided at its upper end with the pin D, adapted to enter the sockethole 9 of the last. To the standard B is also secured the spring E, which serves to throw the pivoted arm 0 for a limited distance toward the rear standard, F. The adjust-able toerest G (shown in perspective in Fig. 4) is provided with the projecting side pins, cl d, which are adapted to enter the inclined series of notches c c c at the opposite sides of the upper end of the standard F, and with the downwardly-projecting rib e, the upper surface f of the rest G being hollowed to fit the front ortoe portion of the last.

Figs. 1 and 3 show the toe-rest G when placed with its oppositepinsd din the second notch c from the extreme upper end of the inclined series of notches, with the rib e resting upon the inclined intermediate surface, a, at the upper end of the standard F, so that the hollowed surfacef of the rest G will extend in nearly a horizontal direction toward the upper end of the arm 0 and pin D, as shown in Fig. 1.

By moving the rest G from notch to notch along the incline a, the jack is made readily adjustable for lasts of difierent sizes, and when the last H is placed upon the pin D of the arm 0 the action of the spring E will serve to throw the arm 0 and last H forward, so that the front portion of the last will rest firmly upon the surface of the rest G.

In order to protect the leather of the boot or shoe from injury, the hollowed surface a of the rest may be covered with leather or other suitable yielding material.

I claim as my invention In a heeling'jack, the combination of the I standard B, pivoted arm 0, provided with the pin D, spring E, standard F, provided at its upper end with the adjacent inclined series of notches c, with an inclined plane surface, a,

between them, and the adjustable toe-piece G, provided with a hollowed upper surface, f, the downwardly-projecting rib e, and the opposite pins d d, which are adapted to enter the notches c, substantially as described.
